- To all whom it mag concern:

Be it known that I,. JAMEs O. BENNETT, a citizen of the United States-ofAmerica, and a residentof Detroit, Wayne county, State of Michigan, haveinvented. certain new and useful Improvements in Revolving Boiler- TubeBlowers, of which the following is a specification. I v

This invention relates to boiler-tube blowers; and it consists of asteam-pipe so constructed and applied to a boiler that the engineer canat any time easily and readily tached. Fig. 2 is a like view of a boilerof.

blow out the tubes and prevent the accumulation of soot or scaletherein.

The invention consists of a steam-pipe centrally located in one of thetubes, provided on its inner end with a cross-arm having blower-headslocated thereon, so that by'rotating the pipe the blowers will bebrought opposite to every and all tubes in the rear end of the boilerfor in ecting steam into all of'them alike. I

In the accompanying drawings, which illustrate my invention, Figure 1.is a side elevation of a boiler of the marine type',-partly in section,showing the blowing device at- ;the stationary ty e, also showing myblowing device attac ed. Fig. 3 is an end; elevation of a boiler,showing the position of the cross arm and the blowers relative to thetubes. Fig. 4 is a sectional view of one of the blowers. Fig. 5 is asectional viewnof a steam-pipe joint. at the forward end of thesteam-pipe, having a lever with a ratchetand-paw attachment-for thepurpose ofgiving rotary motion to the steam-"pipe.

Cis a pipe located in one of the tubes supported in rings or collars DD.These rings have spring-legs d d at each end, by means of which therings are'held in place when forced into the ends of the tubes.

Fig. 6. is a sectional View of a supporting-ringfor' .pose set forth.

E is a cross-arm attached to, the rear end of said pipe C, and upon itare attached two blower-heads F F-one on the extreme end of the arm, soas to reach the outer row of tubes, as shown in Fig. 3, the other blowerplaced on the opposite end of the arm a sufficient distance from the endto have it rotate opposite the end of the inner, row of tubes. Theseheads are made cone-shaped and have radial bores f f for the purpose ofspreading the steam-jets issuing there om.

G is a steam-packed elbow on the end of the pipe C for connecting itwith a vertical "steam pipe H, which in the case of a stationthe tubesthe ipe O is rotated by either the hand-wheel or and-lever. Then theblowers are'successively brought opposite the tubes and thus they maybeblown out in a short time.

Having described my invention, what I claim is' In a boiler-tube blowera pipe rotatably supported in a boiler-tube, a cross-arm on the rear endof-said pipe, blower-heads mounted' onsaid arm, and a packed elbow onthe forward end of said pipe 0, and a ratchet and pawl also mounted onsaid ipe, in combination for operation substantia Signed by me atCleveland, Ohio, this 22d day of June, 1905.
